Question

SSH中配置log4j无效的问题.

Answer 1

这个你参照下面的，修改输出的内容等级就可以了

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### direct messages to file hibernate.log ###
#log4j.appender.file=org.apache.log4j.FileAppender
#log4j.appender.file.File=hibernate.log
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
### set log levels - for more verbose logging change 'info' to 'debug' ###
#log4j.rootLogger=debug, warn, stdout
log4j.rootCategory=WARN, stdout
#log4j.category.org.springframework.beans.factory=DEBUG
#log4j.logger.org.hibernate=info
#log4j.logger.org.hibernate=debug
### log HQL query parser activity
#log4j.logger.org.hibernate.hql.ast.AST=debug
### log just the SQL
#log4j.logger.org.hibernate.SQL=debug
### log JDBC bind parameters ###
#log4j.logger.org.hibernate.type=info
#log4j.logger.org.hibernate.type=debug
### log schema export/update ###
#log4j.logger.org.hibernate.tool.hbm2ddl=debug
### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug
### log cache activity ###
#log4j.logger.org.hibernate.cache=debug
### log transaction activity
#log4j.logger.org.hibernate.transaction=debug
### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug
### enable the following line if you want to track down connection ###
### leakages when using DriverManagerConnectionProvider ###
#log4j.logger.org.hibernate.connection.DriverManagerConnectionProvider=trace

log4j.xml/log4j.properties放在 工程根目录；

分别为每个包设置 级别；

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
    debug="true">
    <appender name="INFO"
        class="org.apache.log4j.DailyRollingFileAppender">
        <param name="File" value="${user.home}/logs/app-info.log" />
        <param name="Append" value="true" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="[%t]%c %d{ISO8601}-- %p -- %m%n" />
        </layout>
        <filter class="org.apache.log4j.varia.LevelRangeFilter">
            <param name="LevelMin" value="INFO" />
            <param name="LevelMax" value="INFO" />
        </filter>
    </appender>
    <logger name="cn.edu.ynu.demo">
        <level value="INFO" />
    </logger>
</log4j:configuration>

那我这个properties怎么配置呢?

Answer 3

你有没有配置对应的包哟，数据库连接包有没有？

追问

你这个问题是和我问的问题不是一个问题吧,我数据库方面完全没有问题,只是没有给你截图而已,而且这个配置是输出一个日志文件,不是连接数据库
